Add up the total power of the devices
For example, the total power of a floor scrubber is equal to the power of the floor scrubber motor, the power of the suction motor, and the power of the drive motor
The total power of the equipment ÷ the voltage of the equipment=the current during discharge
The current during discharge multiplied by the required working hours of the equipment equals the required battery capacity
Note: Due to the size of the device battery compartment, the battery may not meet your requirements (as high-capacity batteries also have a large volume), so we can only choose high-capacity batteries as much as possible to meet your needs.
How to avoid misleading information during the selection of batteries and chargers
Choose the right channel:
Consulting with companies engaged in the battery industry
As is well known, car manufacturers do not produce tires and batteries, refrigerator manufacturers do not generate electricity, and cleaning equipment manufacturers and sellers also do not produce batteries. They do not have professional knowledge in the field of batteries. As far as we know, some sellers of cleaning equipment provide start-up or backup power batteries to users (possibly for unknown reasons), and the battery's usage time is significantly reduced or even fails after 3 months of use. Additionally, some retailers do not guarantee the battery.
Note: Sellers of cleaning equipment can only sell machines without batteries and chargers, and do not mistakenly believe that their machines must use their batteries and chargers (batteries and chargers are completely different industries from cleaning equipment).
Consult with companies engaged in power type batteries
To our knowledge, some users go to the automotive parts market to purchase starter batteries. Salespeople engaged in automotive starter batteries generally do not understand power type batteries, and even if they do, they do not have stock. They usually need to place orders and then transfer goods to companies specializing in power batteries. In addition, companies that use power type batteries are equipped with all intelligent chargers to ensure the service life of the batteries.
Attention when purchasing:
Price:
If the price is too low, it can generally be a starter battery or a regular charger.
Weight of battery:
The capacity of a battery depends on the area of its internal active material, and the main component of lead-acid batteries is lead. The specific gravity of lead is 11.36g/cubic centimeter, so the larger the volume, the larger the capacity. In addition, if the rated capacity of different manufacturers is the same and the weight is compared, in general, whoever is heavier will have more accurate data.
What is the standard for the rated capacity of a battery
Because there are several different discharge rates internationally (i.e. the discharge rate of a battery is expressed in terms of discharge time or the number of hours required to discharge the rated capacity with a certain discharge current), among which the common ones are 20 hour rate, 10 hour rate, and 5-hour rate. The nominal capacity for a 20 hour rate is usually only 85% of the capacity for a 5-hour rate. Therefore, measuring with different standards will result in completely different usage times.
Distinguish the type of charger:
Ask if the charger is specifically designed for power batteries
Ask if the charger is operating at power frequency or high frequency
Ask if the charger has multi-stage charging function
Inform you of the working voltage and capacity of the battery used
Do not use an open-ended battery charger to charge valve regulated lean battery (so-called maintenance free battery).
These two charging curves are different, and the termination voltage is also different. If an open-ended battery charger is used to charge a valve regulated lean battery (so-called maintenance free battery), it will cause overcharging of the valve regulated lean battery (so-called maintenance free battery); Otherwise, it will result in insufficient charging.
